[QUOTE="HallsofIvy, post: 6776293, member: 637751"] Do you mean [tex]x^2[/tex] and [tex]y^2[/tex]? They "got there" because I put them there! And I put them there because I wanted an equation in x and y only. I wanted to eliminate "t" and I knew that, for any [tex]t[/tex], [tex]sin^2(t)+ cos^2(t)= 1[/tex]. [/QUOTE]
